############################################################################
#
# **** TARGETS AND THEIR CORRECT USAGE ****
#
# COMPILATION TARGETS:
# 
# all:		compile all the files
#
# install:	make all, then move the files to the correct directories
#
# remake: 	remove the object files and generated files, and recompile
# 		     NO reconfiguration is done, etc.
#
# depend:	automatically create dependency info
#
# Makefiles:	update Makefile.in and GNUmakefile.in from Makefile.master
#		(only necessary after making changes to Makefile.master)
#
# 'CLEAN' TARGETS:
#
# neat: 	remove object files and generated files (used by remake)
#
# clean:	in addition to neat, also remove .orig and .rej files,
#		cores, lint files, emacs backups, tag files, yacc debug
#		files, generated Makefiles, generated binaries, and
#		generated dependency info
#
# spotless:	make clean, then remove ALL CONFIGURATION AND CUSTOMIZATION
#		     useful for creating distributions
#
# ---- REALLY COMPLEX OPTIONS YOU PROBABLY DON'T WANT TO TOUCH -----
#
# NeXT: link with MallocDebug if you have a NeXT with NeXTOS 2.1 or later and
# you wish to search for memory leaks (see /NextDeveloper/Apps/MallocDebug).
# Note: linking with MallocDebug will cause the virtual size of the
# driver process to reach appoximately 40MB however the amount of real memory
# used will remain close to normal.
#EXTRALIBS=-lMallocDebug -lsys_s

# ---- DO NOT EDIT ANYTHING BELOW HERE UNLESS YOU KNOW ALOT ABOUT HOW
#      MUDOS WORKS INTERNALLY ----
